Which muscle is described as 'soleus' and located close to the heel?

• A. Soleus
• B. Gastroc
• C. Gastrocnemius
• D. Semitendinosus

Answer: (A)

The muscle described as soleus is the deep calf muscle that sits closest to the heel and forms the other part of the Achilles tendon together with the gastrocnemius. It’s a powerful plantarflexor of the foot, especially when the knee is bent. The soleus originates from the tibia and fibula and inserts into the calcaneus via the Achilles tendon, which is why it’s so closely associated with the heel area. The other options don’t fit this description: the gastrocnemius is the more superficial calf muscle that bulges at the back of the leg and crosses the knee, while the semitendinosus is a hamstring muscle in the thigh.
